SAFETY INFORMATION
READ ALL WARNINGS BELOW. FAILURE TO DO SO COULD RESULT
IN SERIOUS PERSONAL INJURY OR DEATH
*RISK OF SUCTION ENTRAPMENT HAZARD, WHICH, IF NOT AVOIDED CAN RESULT IN
SERIOUS INJURY OR DEATH. DO NOT BLOCK SUCTION AT THE PUMP OR IN THE POOL
AS THIS CAN CAUSE SEVERE INJURY OR DEATH
1. Sand Filters are designed to work with water at a temperature > than 32º F and < than 113ºF.
The filter should never be operated outside of these temperatures or damage may occur.
2. The installation should be carried out in accordance to the safety instructions of swimming pools
and the specific instructions for each location.
3. The user should make sure that the installation is carried out by qualified authorized professional
and adhere to local code & regulations. Avoid Electrical Shock – Do Not Use power extension
cords.
4. Connect ONLY to a Ground-Fault Circuit Interrupter (GFCI) power outlet. Consult a qualified,
professional electrician for safe and proper installation of the required electrical outlet.
5. The operating safety of the filter is only guaranteed if the installation and operation instructions
are correctly followed. CAUTION – Check to ensure that air is out of the system before
operation. Any trapped air can cause the tank cover to explode which could result in death,
serious injury, or damage to the system.
6. To reduce the risk of injury, do not permit children to use this product. Install the product at least
10 feet away from the pool to prevent children from using the system to access the pool.
7. Incorrectly installed equipment may fail, causing severe injury, property damage or death.
8. Chemicals and fumes can weaken Swimming Pool/ Spa equipment. Corrosion can cause filters
and other equipment to fail, resulting in severe injury, property damage or death. Do not store
pool chemicals near your equipment. Any modification of the filter requires the prior consent
from the supplier’s original replacement parts and accessories authorized by the manufacturer to
ensure a high level of safety. The supplier assumes no liability for the damage and injuries caused
by unauthorized replacement parts and accessories.
9. In the event of defective operation or fault, contact 877-278-2797 immediately for assistance.
10. DO NOT OPERATE THE SYSTEM WHILE THE POOL IS IN USE.
11. Never Allow Children to Operate this Equipment
How the Sand Filter/Pump Works
Incoming water from the piping system is automatically directed by the Multiport Valve to the top of the filter bed.
As the water is pumped through the filter sand, dirt and debris are trapped by the filter bed, and filtered out. The
filtered water is returned from the bottom of the filter tank, through the Multiport Valve and back through the
piping system.
Preparation Before Installation
1． The filter should be placed on a level concrete slab, very firm ground, or equivalent.
Ensure that the ground will not subside, preventing any strain from the attached
plumbing.
2． Position the filter under consideration of the piping connections, so that it is
convenient for operating and servicing.
3． Ensure that the compliance label is facing the front to allow easy identification in the
case of service difficulties.
How to Install the System
INSTALLATION
1. Mount the pump to sand filter support by using bolts and nuts.
2. Install the drain plug assembly to sand tank as below pictures.
3. Press and turn the sand tank to mount it to sand filter support with correction direction (drain plug is at
outside as below picture).
4. Insert the tube with the diffuser body inside the tank as above picture, then place the funnel on the tank’s
mouth and pour 45lbs of the No. 20 Silica Sand with particle size of 0.45 mm-0.55mm sand into the tank
5. Take away the funnel, and then clean really carefully the tank’s neck and fix the valve with O-ring through
flange clamp set. (the direction of “PUMP” port on valve needs to face pump out port)
6. Connect the sand tank to pump with hose, hose clamps and hose adaptors.
Installation Notes
1． Ensure solvents are not excessively applied to fittings as this could run into O-ring and create sealing
problems.
2． Do not over tighten fittings or adapters
HOW TO USE
1． Inspect all the connections have been made correct and are secure.
2． Depress top mount valve handle and rotate to BACKWASH position.
3． Prime and start pump according to pump instructions.
NOTE: ALL SUCTION AND DISCHARGE VALVES MUST BE OPENING WHEN STARTING THE
SYSTEM. FAILURE TO DO SO COULD CAUSE SEVERE PERSONAL INJURY. MAKE SURE THE
FILTER VESSEL ARE FULLY FILLED THE WATER BEFORE STARTING UP THE PUMP OR IT WILL
CAUSE THE PUMP DAMAGED.
4． Once water flow is steady out the waste line, run the pump for at least 2 minutes. The initial back-washing of
the filer is recommended to remove any impurities of fine sand particles in the sand media.
5． Turn pump off and set valve to RINSE position. Start pump and operate until water in sight glass is
clear----about 1/2 to 1 minute. Turn pump off, set valve to FILTER position and restart pump. Your filter is
now operating in the normal filter mode, filtering particles from the pool water.
NOTES:
1． Note the initial pressure gauge reading when the filter is clean. (it will vary from pool depending upon the
pump and general piping system). As the filter removes dirt and impurities from the pool water, the
accumulation in the filter will cause the pressure to rise and flow to diminish. When the pressure gauge
reading is 8-10 PSI higher than the initial “clean” pressure you noted, it is the time to backwash (clean) the
filter.
2． IMPORTANT: To prevent unnecessary strain on piping system and valving, always shut off pump before
switching filter control valve position.
3． To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and
skimmer baskets regularly.
FILTER CONTROL VALVE FUNCTIONS：
FILTER - Set valve to FILTER for normal filtering. Also use for regular vacuuming.
BACKWASH – For cleaning filter. When filter pressure gauge rises 8-10 PSI above start-up (clean pressure):
Stop the pump, set valve to BACKWASH. Start pump and backwash until water in sight glass is clear.
Approximately 2 minutes or less depending on dirt accumulation. Proceed to RINSE.
RINSE – After backwashing, with pump off, set valve to RINSE. Start pump and operate for about 1/2 to 1
minute. This ensures that all dirty water from backwashing is rinsed out of the filter to waste, preventing possible
return to the pool. Stop pump, set valve to FILTER and start pump for normal filtering.
WASTE – To bypass filter for draining or lowering water level and for vacuuming heavy debris directly to waste.
